This book constitutes the proceedings of the 17th China National Conference on Computational Linguistics, CCL 2018, and the 6th International Symposium on Natural Language Processing Based on Naturally Annotated Big Data, NLP-NABD 2018, held in Changsha, China, in October 2018. The 33 full papers presented in this volume were carefully reviewed and selected from 84 submissions. They are organized in topical sections named: Semantics; machine translation; knowledge graph and information extraction; linguistic resource annotation and evaluation; information retrieval and question answering; text classification and summarization; social computing and sentiment analysis; and NLP applications.

Chinese Computational Linguistics and Natural Language Processing Based on Naturally Annotated Big Data

Abstract: My dissertation comprises three chapters on industrial organization and health economics. The first Chapter studies a monopolist's product launch strategy. The second Chapter studies credence goods markets. The third chapter analyzes informal payments in public health sectors of developing countries. In the first Chapter, joint with Pasquale Schiraldi, we study how a monopolist should launch a new product to distinct markets when the uncertainty of the product's quality is resolved over time. We examine how the monopolist may influence consumer learning by manipulating the launch sequence when the monopolist and consumers can learn about the quality of the product from previous sales. Depending on the price of the product and the general reputation of the product, the monopolist may prefer a sequential launch to a simultaneous launch. We derive the optimal number of markets in which the monopolist will launch the product in each period. The monopolist's dynamic equilibrium strategy endogenizes informational herding. In the second Chapter, I study credence goods markets when an expert is either selfish or conscientious. A selfish expert is a profit maximizer. A conscientious expert wants to maximize profit and repair the consumer's problem. In a monopoly model, there are only uniform-price equilibria and nonuniform-price equilibria. I study whether a consumer can infer the expert's type from his equilibrium price list and analyze the efficiency of an equilibrium. Finally, I check the robustness of each class of equilibria for a competitive setting. In the third Chapter, joint with Monic Jiayin Sun, we study informal payments in public health sectors of many developing countries. Such payments are made by patients to providers for services which are supposed to be supplied by public health care sectors. Informal payments are made because the allocation mechanism in the public sector fails to take into account provider or patient circumstance. We compare welfare implications of different policies that regulate informal payments. Patient and provider heterogeneity play a central role in the comparison.

AsiaInformationRetrievalSymposium(AIRS)2008wasthefourthAIRSconf- ence in the series established in 2004.The ?rst AIRS washeld in Beijing, China, the second in Jeju, Korea, and the third in Singapore. The AIRS conferences trace their roots to the successful Information Retrieval with Asian Languages (IRAL) workshops, which started in 1996. The AIRS series aims to bring together international researchers and dev- opers to exchange new ideas and the latest results in information retrieval. The scope of the conference encompasses the theory and practice of all aspects of information retrieval in text, audio, image, video, and multimedia data. We are pleased to report that AIRS 2006 receiveda largenumber of 144 s- missions. Submissions came from all continents: Asia, Europe, North America, South America and Africa. We accepted 39 submissions as regular papers (27%) and 45 as short papers (31%). All submissions underwent double-blind revi- ing. We aregratefulto all the area Co-chairswho managedthe review processof their respective area e?ciently, as well as to all the Program Committee m- bers and additional reviewers for their e?orts to get reviews in on time despite the tight time schedule. We are pleased that the proceedings are published by Springer as part of their Lecture Notes in Computer Science (LNCS) series and that the papers are EI-indexed.
